set_cell(slab.cell, scale_atoms=True) # 将水层晶胞设置为与Ni相同。参数scale_atoms=True表示在改变晶胞大小的同时,相应地缩放水层中原子的位置 zmin = W.positions[:, 2].min() # 计算水层中所有原子在z轴上的最小坐标值 zmax = slab.positions[:, 2].max() # 计算Ni层中所有原子在z轴上的最...
Edit-Edit Cell,可以修改晶胞大小,周期性,改真空层大小。 扩胞 View-Repeat,修改Repeated atoms,分别是xyz三个方向扩大的倍数。如果只是想查看重复结构,输入即可,并不会改变原来的结构;如果想修改,让扩胞后的结构作为unit cell,就点Set unit cell。
然后计算由原子到分子的分子结合能:E_结合 = E_N2 - 2E_N。你可以在计算开始之前设置atoms.set_initial_magnetic_moments([3])来告诉GPAW你的原子是具有自旋极化的。 练习答案 from ase import Atoms from ase.io import Trajectory from gpaw import GPAW atoms = Atoms('N2', positions=[[0, 0, -1],...
默认值是scale_atoms=False,表示单元格更改时笛卡尔坐标保持不变。 >>> W.set_cell(slab.cell, scale_atoms=True) >>> zmin = W.positions[:, 2].min() >>> zmax = slab.positions[:, 2].max() >>> W.positions += (0, 0, zmax - zmin + 1.5) 最后我们将水复制到平板上: >>> interface...
